為什么會出錯
package aa;
public class aa {
String a = "品牌 = 愛國者f928";
double b=12.4;
String c="內置鋰電池";
int d=499;
System.out.println(a);
System.out.println(b);
System.out.printin(c);
System.out.println(d);
}

1.沒有main主方法，2.System.out.printin(c);這條代碼里的println給你打錯了

System.out.println(c);
System.out.println(d);

}
會不會是你l打成了i。就是第三個輸出c那個。
